You don`t do that,the computer will loose it`s memory,the dealer will have to re-flash the computer,that only works on the older models,like 1994 and back.

After engine bay was washed the engine check light came on how do i remove the fault


You can try resetting the main computer by just disconnecting the battery and let it sit for 10 minutes with no battery, connect the battery back and that should reset all sensor lights. If that doesn't work check all sensor connections, that power wash could of disconnected the Map sensor or other cirtical connections attached to other sensors in the engine compartment.
Worse case scenario is that the bay wash could of pushed or flushed some debris into that Map sensor housing and is now clogged up, a simple cleaning with a special spary cleaner for Map sensors could make the check engine light turn off.

Try disconnecting negative battery cable for a few minutes then reconnect. This will reset computer. Worked on my wife's car. It would start and shut off 2 seconds later for no apparent reason. Do you have a check engine light on? Could also be caused by a bad maf/map sensor or tps sensor

Engine management fault fitted map sensor and still wont start


Check that the hose for the MAP sensor is not disconnected or blocked. Then check that the vacuum port for the hose is clear on the engine side. After that, start looking at a shorted wire.

lost power to the mAP, check the power pin.
lost ground to sensor.
lost vacuum to the sensor (clogged paths)
Bad MAP sensor Water/dirt intrusion affecting MAP sensor connector Intermittent open in the reference, ground, or signal wire for the MAP sensor Intermittent short in the reference, ground, or signal wire for the MAP sensor Ground problem due to corrosion causing intermittent signal problem A break in the flexible air intake duct between the MAF and the intake manifold Bad PCM
(do not assume the PCM is bad until you've exhausted all other possibilities)

How long does it take check engine light to go off after map sensor is replaced. Car is a 1998 buick leSabre. Code reader pointed to map sensor. I understand it takes several starts for light to reset so...


you can take of the ground of the battery of the car for 30 minutes and the computer will reset. if you drive around without reseting the computer might figure it out after 30 miles.

Hold light blinking, check engine light on, engine slows down


check tps sensor (throttle position sensor in backside of the throttle cable) and map sensor (manifold absolute pressure on front little 1 inch sensor with vacuum line) make sure there plugged in. the ecm (engine control module driver side inner fender) and tcm (transmission control module under dash) both need the data to know when to upshift and increase fuel/air. Otherwise the computer runs default values and guesses off of other sensors giving poor performance. also disconnect battery for 15 min. usually resets aveo service lights if you dont have a scanner.
